Apple has begun testing two Audio Intelligence features that bring ambient listening to Apple Watch: Siri Recap takes notes on conversations throughout the day, and Live Rewind lets users retrieve the last 15 seconds as text. Both appear in the first developer beta of watchOS 27.3, released on November 3, and are intended for Apple Watch Series 12 and Ultra 4.
The beta's arrival launches a proposal Apple introduced in September alongside those watches. It also opens a discussion about what it means to carry a device that processes nearby conversations, although the company maintains that it does not create or store audio recordings. The features are still in beta and, for now, will be offered only in English and outside the European Union.
Two features with different behaviors
Siri Recap is the option that listens ambiently when the user chooses to activate it. Throughout the day, it generates a title and key points about conversations, which users can review later in the Siri app on iPhone. Apple presents it as a way to remember what was said without having to focus on taking notes.
The summary is not intended to be a complete transcript. Apple describes it as a high-level summary and says it does not attribute statements to specific people. It does not label anyone as “Speaker A” or “Speaker B,” although names mentioned in the conversation could appear in the summary. The company also says it filters certain potentially harmful content and sensitive data, such as financial information, government identifiers, and authentication data.
Live Rewind works differently: the user double-presses the Digital Crown, and the watch displays a text snippet of what was said during the previous 15 seconds. The user can ask Siri about that text or save it in the Siri app. If it is neither saved nor used for a query, the snippet disappears about 30 seconds after the screen turns off, according to Apple's documentation.
Siri Recap ambiently takes notes on your conversations throughout your day and creates high-level Apple Intelligence–generated summaries that you can use later to jog your memory, so you can stay present in the moment.

Apple thus distinguishes a tool activated on demand from another that can collect material to create summaries throughout the day. MacRumors describes Siri Recap as a feature that works in the background, while Live Rewind displays text only after a double press. Both features are optional, but users must enable them.
Controls, alerts, and deletion
Siri Recap is configured in the Watch app on iPhone. Users can schedule its activity by time, location, or both—for example, limiting it to work or preventing it from activating at night—and can also turn it on or off manually from the watch's Control Center. Apple says the device alerts users when the summary starts or stops according to the selected schedule.
Live Rewind also requires prior activation. When used, the watch plays a sound even if it is muted or connected to headphones. The screen displays a full-screen animation and a microphone indicator. Apple presents these signals as alerts for people nearby; Gizmodo, by contrast, questions whether alerts of this kind are enough to address the issue of consent from people involved in a conversation.
Siri Recap summaries can be automatically deleted after up to seven days, unless the user saves them. Live Rewind text is not retained by default. If saved, summaries and snippets appear in the Siri app and can be synced with iCloud using end-to-end encryption, provided two-factor authentication and a passcode are enabled on the device. Apple says it does not possess the encryption keys.
The company also lets users review, edit, export, and delete summaries from the Siri app. According to Apple, deleting an item removes it from all synced devices. The export option includes other apps, such as Notes and Journal.
What Apple says about audio
Apple's technical explanation centers on the S11 chip and its Secure Exclave, a hardware-isolated environment that processes sensor data. The company says raw audio passes through a protected buffer and is deleted after processing; no recordings are created or saved and, according to Apple, neither the operating system, apps, the user, nor the company itself can access that audio.
Processing is not identical for the two features. Live Rewind and speech recognition are processed on the device. If the user asks Siri a question about the snippet or saves it in the app, that content is securely sent to Private Cloud Compute. For Siri Recap, encrypted audio passes from the watch to the paired iPhone, where it is transcribed and condensed inside the Secure Exclave. Encrypted, shortened text is then sent to Private Cloud Compute to generate the summary. Apple describes this text as less than half the length of the original transcript.
Apple maintains that Private Cloud Compute does not store this data or allow the company to access it. The text result is returned to the iPhone and watch in encrypted form. The documentation nevertheless warns that summaries may be incomplete or inaccurate and could omit or misinterpret important details; it recommends checking the information when accuracy matters.
The protections Apple describes do not eliminate all concerns about use in private conversations. Gizmodo notes that people near a watch might not know their words are being processed, and points out that visual and audio alerts on other AI recording devices can also be bypassed. The publication calls the issue potentially problematic from a legal standpoint in some states, without identifying which ones.
Compatible models and availability
The features require an Apple Watch Series 12 or Ultra 4 and an iPhone compatible with Apple Intelligence. MacRumors and Engadget say an iPhone 16 or later is required, but exclude the iPhone 16e; Apple's support page also lists models in the iPhone 17 family, iPhone Air, iPhone 18 Pro, and iPhone Duo. Apple does not include the iPhone 16e in that list.
Apple Support specifies that Siri Recap and Live Rewind are unavailable to users under 18. MacRumors, on the other hand, says they are unavailable to users under 13 and adds that child accounts for users under 18 require parental approval. The difference between these age limits appears in the descriptions published by Apple and MacRumors.
The initial beta works in English, and the features are not offered in the European Union or China. Apple attributes the European exclusion to the requirements of EU technology regulations and said in a statement: “Apple is working constructively with the EU in an attempt to find a path forward”. Apple also notes that some features that rely on server-based models are subject to daily usage limits.
Apple introduced Audio Intelligence in September as a suite that, in addition to Siri Recap and Live Rewind, includes sound recognition—such as sirens, alarms, and doorbells—and automatic music recognition with Shazam. Sound Recognition and Shazam were already available on the watch, according to MacRumors; the two new features are the ones arriving in the beta now.
Apple had announced that Live Rewind and Siri Recap would arrive in beta in late 2026. The company has not set a specific public date for general availability in its documentation; Gizmodo places the full public rollout in December, and MacRumors also expects watchOS 27.3 to launch that month. For now, access is limited to those who install the developer beta.
